NJ-series CPU Unit Motion Control User’s Manual (W507)
Set the following axis parameters if you want to jog when home is not defined. The following setting
example is for a one-axis device.
*1
If there is more than one axis, a different variable name is set for each axis.
*2
If there is more than one axis, a different value is set for each axis.
*3
Set the node address to the same value as the node address that is set on the Servo Drive. If there is more
than one axis, a different value is set for each axis.
*4
The position command unit will be 1
µ
m.
*5
The maximum velocity will be 3,000 r/min = 30 m/min = 0.5 m/s = 500,000
µ
m/s.
*6
The maximum jog velocity will be 10% of the maximum velocity, i.e., 0.05 m/s = 50,000
µ
m/s.
*7
The maximum acceleration and the maximum deceleration are 5 m/s
2
. The acceleration time to the maximum
velocity (3,000 r/min) is 0.1 s.
This section describes the settings for the MC_MoveJog input variables
Velocity
(Target Velocity),
Acceleration
(Acceleration Rate), and
Deceleration
(Deceleration Rate).
•
For example, set
Velocity
to 30,000 to jog at a velocity of 0.03 m/s.
•
Set
Acceleration
and
Deceleration
to 3,000,000 to accelerate and decelerate at 3 m/s
